In this tutorial, you will learn how to build people counters using OpenCV and Python. Using OpenCV, we will calculate the number of people entering or leaving the department store in real time. In the first part of today's blog post, we will discuss how to use both to create more accurate people counters. After that, we will look at the direc ...

If you want to complete the project, I will put the github link at the end of the article: You can see that the final identification license plate number is min G99999. In fact, I accidentally thought of doing a small project with c + + in the winter of the previous year, and then realized the license plate extraction and segmentation with c+ ...

Binocular vision is based on geometric mathematics, and mathematical derivation is boring. Therefore, I will not introduce the mathematical principles here, but briefly describe the process of binocular vision. Binocular vision mainly includes five parts: camera calibration, image distortion correction, camera correction, image ...

In object detection, due to the limitations of cost and application occasions, we can't blindly increase the resolution of the camera, or we have used a camera with high resolution, but the field of view is large and still can't achieve high accuracy. At this time, we should consider sub-pixel technology, which is to further subdivide between t ...

1 basic knowledge of image 1.1 digital image A two-dimensional image can be represented by a matrix or array. We can understand it as a binary function f ( x , y ) ...

Recently, many children are learning Python and want to find a fun hand training project. Let's share a simple Python project for beginners today. This article will take blibli – ride the wind and waves video as an example, you get to download the video. At the same time, python is used to climb the video barrage of station B, opencv i ...

1. Download Mobile Software You need to download the IP camera software on the mobile phone. You can turn the mobile device into a wireless IP camera with two-way audio support through the built-in RTSP and HTTP server and use it for security monitoring. You can use the browser on the computer to view it. Here I use OpenCV to read the video st ...

Geometric transformation Geometric transformation refers to the operation of mapping one image to another. zoom Use function CV2 Resize() to zoom the image dst = cv2.resize( src, dsize[, fx[, fy[, interpolation]]] ) dst represents the output target image. The type of the image is the same as src, and its size is dsize (when the value ...
